BSc NURSING - 3rd SEMESTER ASSIGNMENT

---

1. INTRODUCTION

• COPD (Chronic Obstructive Pulmonary Disease) is a chronic, progressive lung disease that causes airflow obstruction and breathing difficulty.
• It is one of the leading causes of morbidity and mortality worldwide; ranked as the 3rd most common cause of death globally (WHO, 2023).
• COPD mainly includes two conditions: Chronic Bronchitis and Emphysema, which often coexist in the same patient.
• The disease is largely preventable - cigarette smoking is responsible for 85-90% of all COPD cases.
• Early diagnosis and proper nursing management can slow disease progression, reduce exacerbations, and greatly improve quality of life.

---

2. DEFINITION

• Chronic Bronchitis: Persistent productive cough for at least 3 consecutive months in 2 or more consecutive years.
• Emphysema: Permanent enlargement and destruction of air spaces distal to the terminal bronchioles, with loss of elastic recoil.

---

3. ANATOMY & PHYSIOLOGY (Related to COPD)

• Airways: Nose → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli
• Lungs: Two lungs (right = 3 lobes, left = 2 lobes) covered by pleura
• Alveoli: Tiny air sacs where gas exchange (O2/CO2) takes place; walls are thin and elastic
• Diaphragm: Main muscle of breathing; contracts during inspiration
• Goblet cells: Produce mucus to trap particles in airways
• Cilia: Hair-like structures that move mucus up and out of airways (mucociliary escalator)

• Ventilation: Air moves in and out of lungs (tidal volume = 500 mL normally)
• FEV1 (Forced Expiratory Volume in 1 second): Normal = >80% predicted
• FVC (Forced Vital Capacity): Volume of air forcefully expelled after deep breath
• FEV1/FVC ratio: Normal = >0.70 (70%); In COPD = <0.70 (obstructed)
• Oxygen: PaO2 normal = 80-100 mmHg; CO2: PaCO2 normal = 35-45 mmHg
• Gas exchange: O2 diffuses into blood; CO2 diffuses out at alveolar-capillary membrane

• Cigarette smoke/pollutants → Airway inflammation → Goblet cell hyperplasia → Excess mucus production
• Destruction of alveolar walls → Loss of elastic recoil → Air trapping → Barrel chest
• Airway narrowing → Increased resistance → Reduced airflow (↓ FEV1)
• V/Q mismatch → Hypoxemia (low O2) + Hypercapnia (high CO2)
• Progressive changes lead to cor pulmonale (right-sided heart failure) in advanced stages

4. ETIOLOGY / CAUSES

1. Cigarette Smoking - Most important cause; responsible for 85-90% of COPD cases
2. Second-hand / Passive Smoking
3. Occupational Exposure - Coal dust, silica, cadmium, grain dust
4. Indoor Air Pollution - Biomass fuel smoke (wood, cow dung) from cooking in poorly ventilated homes
5. Outdoor Air Pollution - Vehicle exhaust, industrial pollutants
6. Recurrent Respiratory Infections - Especially in childhood
7. Poorly controlled asthma

1. Genetic factors - Alpha-1 antitrypsin (AAT) deficiency (panacinar emphysema)
2. Age - Risk increases with age (usually >40 years)
3. Gender - More common in males; but rising incidence in females
4. Low socioeconomic status
5. Premature birth / low birth weight - Affects lung development
6. Airway hyperresponsiveness

6. SIGNS & SYMPTOMS

• Chronic productive cough (especially in the morning)
• Increased sputum production (white or clear)
• Mild dyspnea (shortness of breath) on exertion
• Frequent respiratory infections (colds, bronchitis)
• Mild wheezing
• Reduced exercise tolerance / easy fatigue

• Severe dyspnea at rest (cannot speak in full sentences)
• Barrel chest (A-P diameter increased due to air trapping)
• Pursed-lip breathing
• Use of accessory muscles (sternocleidomastoid, intercostal) for breathing
• Cyanosis (bluish discoloration of lips and fingertips) - "Blue Bloater" in bronchitis type
• Pink puffer appearance (thin, pink, pursed-lip breathing) - emphysema type
• Digital clubbing (chronic hypoxia)
• Cor pulmonale: JVD, pedal edema, hepatomegaly
• Weight loss and muscle wasting
• Polycythemia (↑ RBCs as compensatory response to chronic hypoxia)

8. MEDICAL MANAGEMENT

• Controlled O2: 1-2 L/min via nasal cannula (target SpO2 = 88-92% in COPD to avoid hypercapnia)
• Long-Term Oxygen Therapy (LTOT): >15 hours/day for PaO2 < 55 mmHg at rest
• Venturi mask: Delivers precise FiO2 (24%, 28%, 35%, 40%) - preferred in COPD
• High-flow nasal oxygen (HFNO) for severe exacerbations

• BiPAP: Used in acute exacerbations with hypercapnic respiratory failure
• CPAP for nocturnal use if obstructive sleep apnea coexists

• Lung Volume Reduction Surgery (LVRS) for severe emphysema
• Bullectomy: Removal of large bullae
• Lung Transplant: For end-stage COPD (FEV1 < 20%)
• Bronchoscopic lung volume reduction (endobronchial valves)

---

9. NURSING MANAGEMENT

A. Nursing Assessment

• "I cannot breathe properly," "I feel breathless all the time"
• History of smoking (pack-years = packs/day × years smoked)
• Chronic cough - duration, frequency, character
• Sputum - color, amount, consistency (yellow/green = infection)
• Dyspnea scale: MRC Dyspnea Scale 0-4
• History of previous exacerbations, hospitalizations
• Occupational history - dust, chemical exposure
• Medication history - inhalers used, compliance
• Ankle swelling, fatigue, weight loss
• Functional limitations in ADL

• Vital Signs: Tachycardia (HR > 100), tachypnea (RR > 20), low SpO2 (< 90%)
• Barrel chest, use of accessory muscles, pursed-lip breathing
• Auscultation: Decreased breath sounds, wheezes, rhonchi, prolonged expiration
• Percussion: Hyperresonance (air trapping)
• Cyanosis: peripheral (fingertips) or central (lips)
• Digital clubbing, pedal edema (cor pulmonale)
• ABG: Hypoxemia, hypercapnia, respiratory acidosis
• Spirometry: FEV1/FVC < 0.70
• CXR: Hyperinflated lungs, flattened diaphragm

B. Nursing Diagnoses (NANDA Format)

1. Ineffective airway clearance Related to: Excessive mucus production, airway inflammation, ciliary dysfunction As evidenced by: Productive cough, abnormal breath sounds (rhonchi/wheezes), dyspnea
2. Impaired gas exchange Related to: Destruction of alveolar walls, V/Q mismatch, alveolar hypoventilation As evidenced by: PaO2 < 60 mmHg, SpO2 < 90%, PaCO2 > 45 mmHg, confusion/restlessness
3. Ineffective breathing pattern Related to: Air trapping, hyperinflation, respiratory muscle fatigue As evidenced by: Use of accessory muscles, barrel chest, pursed-lip breathing, RR > 24/min
4. Activity intolerance Related to: Imbalance between O2 supply and demand, fatigue, dyspnea on exertion As evidenced by: Reports fatigue and dyspnea with minimal activity, reduced 6MWT distance

10. HEALTH EDUCATION

• SMOKING CESSATION: Stop smoking immediately - single most effective intervention; NRT or varenicline may be prescribed
• INHALER TECHNIQUE: Correct use of MDI with spacer and DPI; shake - exhale - seal lips - inhale slowly - hold 10 sec - rinse mouth after ICS
• MEDICATIONS: Take as prescribed; carry rescue inhaler (Salbutamol) at all times; never stop without medical advice
• BREATHING EXERCISES: Pursed-lip breathing during exertion; diaphragmatic breathing 10 min twice daily
• DIET: Small, frequent, high-calorie, high-protein meals; avoid gas-forming foods; stay hydrated (2-3 L/day unless restricted)
• ACTIVITY: Balance rest and activity; enroll in pulmonary rehabilitation; gradually increase walking distance
• INFECTION PREVENTION: Annual influenza vaccine; pneumococcal vaccine every 5 years; handwashing; avoid crowds during flu season
• WARNING SIGNS to report: Increased/colored sputum, severe breathlessness, chest pain, cyanosis, confusion, ankle swelling, fever > 38°C
• FOLLOW-UP: Clinic visits every 3-6 months; spirometry yearly; carry COPD action plan card
